Posted on Wednesday, October 31 2007 @ 02:16:13 CET by

Elpida debuts new ultra-low voltage mobile DDR2 memory chips that operate at 1.2V.

Elpida's Mobile RAM is now used in many high-performance 2.5G and 3G mobile phones, which in recent years have gone beyond music downloading and website surfing to offer such high-performance features as video viewing, video recording and video output. Given expectations of growth in high-definition (HD) video functions, products that can rapidly process high-resolution graphics and other high-density data will become increasingly important.

The main features of DDR2 Mobile RAM are as follows:
  • Advanced development of DDR2 Mobile RAM compliant with the JEDEC LPDDR2 specification now undergoing final standardization.
  • Including the DRAM core operates at 1.2V versus 1.8V for DDR Mobile RAM 1.2V high-speed operation achieved using 70nm process technology (now in use in mass production) and new peripheral circuit technology. Ultra-low voltage alley block and ECC circuits that use global top-level technology enabled dependable functionality with 1.2V I/O and low self-refresh current.
  • 533Mbps high-speed functions based on the DDR2 interface
  • Partial alley self refresh (PASR), automatic temperature compensation self refresh (ATCSR), deep power down (DPD) and other standardized Mobile RAM special low-power functions enable a longer battery operating time.
  • Elpida will begin sampling its newly developed DDR2 Mobile RAM in November 2007.
